+# Задание: Hermes Hub — Release Recovery + GitHub Auto Update
+
+## Дата поступления
+2026-08-20
+
+## Область задачи (Scope)
+1. **Independent Audit & Remediation Tracker**:
+   - Сохранение `docs/audits/2026-08-20-independent-audit.md`.
+   - Ведение `docs/audits/2026-08-20-remediation-tracker.md` со всеми ID, приоритетами, статусами и тестами.
+2. **Unified Version Source (v0.1.1)**:
+   - Создание единого источника истины версии `version.py`.
+   - Синхронизация `pyproject.toml`, `compatibility.json`, GUI About, CLI, Installer, Updater, Diagnostics.
+3. **P0 Blockers Resolution (9/9 VERIFIED)**:
+   - P0-1: `customtkinter` / `Pillow` чистая установка в venv Hermes + проверка импортов.
+   - P0-2: Унификация `ProfileAuthManager.get_profile_dir(profile_id)`.
+   - P0-3: `json` импорт в `add_account_wizard.py` + тест сохранения API key.
+   - P0-4: Реализация `AutoAssigner.auto_assign_all()`.
+   - P0-5: Antigravity failover & typed exceptions (ошибки провайдера не возвращаются как успешный ответ).
+   - P0-6: Унификация статусов OAuth (`pending`, `success`, `failed`, `cancelled`, `timeout`).
+   - P0-7: Реальный обработчик кнопки `assign_role`.
+   - P0-8: Применение выбранной роли из Wizard в конфигурацию.
+   - P0-9: Удаление фейковой валидации API ключей (реальная проверка или `NOT_VERIFIED`).
+4. **P0 Release Test & Isolation**:
+   - `tests/test_p0_release_gate.py`.
+   - Изоляция тестов через `HERMES_HOME` (tmp_path), запрет модификации реальных файлов пользователя.
+   - Pytest маркеры (`unit`, `integration`, `network`, `installer`, `live`).
+5. **Router, Health & Performance Fixes**:
+   - Background snapshot updates, устранение фризов `_restore_status()`, bounded parallelism в `scan_all`.
+   - In-place UI update без мерцания.
+   - Cooldown recovery & разделение здоровья профиля и семейств моделей.
+   - Session affinity TTL и inter-process lock для `router_state.json`.
+   - Безопасное окружение subprocess (whitelist env vars).
+   - Error taxonomy и round-trip конфигурации.
+6. **Security & Cleanup**:
+   - Единый `paths.py`.
+   - Санитизация логов (маскирование токенов/ключей).
+   - Вывод устаревшего веб-стека (`gui_server.py`, `gui_cockpit.html` -> legacy) и удаление FastAPI/uvicorn из runtime.
+7. **Packaging, Installer & Single Instance**:
+   - Канонический инсталлятор с pre-flight проверкой версии Hermes и зависимостей UI.
+   - Single Instance mutex.
+   - Запись `startup.log` до инициализации UI.
+8. **CI/CD & Built-in Auto Updates**:
+   - GitHub Actions CI на чистом Windows runner.
+   - Релизный пайплайн `v0.1.1`.
+   - Встроенный механизм проверки и установки обновлений через `HermesHubUpdater` с защитой от поврежденных файлов (SHA-256) и rollback.
+   - E2E dogfood update test v0.1.1 -> v0.1.2.
+   - `scripts/release_gate.py`.
+9. **Документация и Финальный Отчёт**:
+   - Обновление всей документации (`README.md`, `ARCHITECTURE.md`, `AUTH.md`, `SECURITY.md`, `INSTALLATION.md`, `UPDATES.md`, `DEVELOPMENT.md`, `ROUTER.md`).
+   - Итоговый аудит `docs/audits/2026-08-20-release-recovery-results.md`.

+# Независимый аудит релиза Hermes Hub
+
+**Дата**: 2026-08-20  
+**Репозиторий**: `https://github.com/ochenstarik-ui/hermes-hub`  
+**Проверенная ревизия**: `origin/main @ 5ccfd48`  
+**Текущая заявленная версия**: 0.1.0  
+**Целевая версия релиза**: 0.1.1  
+
+---
+
+## 1. Сводка результатов аудита
+
+Независимый аудит выявил ряд критических архитектурных и прикладных несоответствий, требующих обязательного исправления (Release Gate Blockers):
+
+### P0 (Блокеры релиза — 9 пунктов)
+1. **P0-1 (customtkinter / Pillow imports)**: На чистой системе без установленных в venv пакетов `customtkinter` / `Pillow` приложение аварийно завершается без внятного сообщения.
+2. **P0-2 (ProfileAuthManager.get_profile_dir signature)**: Несогласованность сигнатуры метода `get_profile_dir` (`provider, profile_id` vs `profile_id`).
+3. **P0-3 (Missing `import json` in wizard)**: В `add_account_wizard.py` отсутствует `import json`, что приводит к падению при попытке сохранить API-ключ для Codex / OpenCode Go.
+4. **P0-4 (AutoAssigner.auto_assign_all)**: UI вызывает несуществующий метод `AutoAssigner.auto_assign_all()`, вызывая ошибку `AttributeError`.
+5. **P0-5 (Antigravity failover & error handling)**: `agy_generate` возвращает текст ошибки провайдера как обычный успешный ответ модели (`choices[0].message.content`), из-за чего RouterEngine не распознаёт ошибку квоты и не выполняет failover.
+6. **P0-6 (OAuth session status handling)**: Неунифицированные статусы OAuth сессий приводят к зависанию визарда на 120 секунд вместо немедленной реакции на ошибку.
+7. **P0-7 (assign_role button handler)**: Кнопка «Назначить» не имела реального диалога и обработчика назначения роли с сохранением в конфигурацию.
+8. **P0-8 (Wizard role application)**: Выбранная на 4 шаге визарда роль не применялась к реальной конфигурации роутера.
+9. **P0-9 (Fake API validation)**: В визарде присутствовала заглушка «успешно проверено» без реальной валидации ключа и обнаружения моделей.
+
+---
+
+## 2. Категории P1 / P2 / P3
+
+- **P1 (Архитектурная корректность)**: Изоляция тестов через `HERMES_HOME` (tmp_path), офлайн pytest по умолчанию, background health snapshot, in-place UI обновления, разделение здоровья профиля и моделей, TTL сессионной привязки, блокировка `router_state.json`, изоляция переменных окружения subprocess, санитизация логов, удаление мертвого FastAPI веб-стека.
+- **P2 (Дистрибуция и надежность)**: Канонический инсталлятор, проверка совместимости версий Hermes (`compatibility.json`), ресурсная иконка в .exe, Single Instance mutex, `startup.log`.
+- **P3 (Автообновления и CI/CD)**: GitHub Actions CI, встроенный `HermesHubUpdater` с верификацией SHA-256, поддержка отката (rollback), E2E dogfood update test `v0.1.1 -> v0.1.2`, скрипт `scripts/release_gate.py`.
